Apterous viviparous female (8 specimens) Morphological characters: Body medium-sized, broadly oval, 1,83-2.57 mm long. Head, antennae, legs and siphunculi blackish sclerotic. Arms of mesothoracic furca separate. Sclerotic pattern of dorsum rather extensive, consisting of an entire band across pronotum, a medially divided transverse band on mesonotum, entire transverse bands across abdominal tergites 6-8 inclusive, paired spinal sclerites and much smaller pleural ones on intervening tergites and very small marginal sclerotices bearing marginal tubercles; intersegmental muscle scleroites very pronounced. Spinal tubercles usually paired on head and abdominal tergite 8, rarely a single one also present on tergite 7. Marginal tubercle rather small and convex present typically on pronotum and abdominal segments 1-5 and 7, rarely (in 30% of specimens) also on tergite 6; those on tergite 7 usually paired. Pronotum without pleural hairs. Dorsal abdominal hairs rather short, those on anterior tergites blunt, maximally 8-15 urn long, on tergite 8 about 15-20 urn long. Ventral hairs acute, maximally 18-25 urn long. Antennae 6-jointed, relatively slender, about 0.49-0.68 of body length, without secondary rhinaria. Processus terminális 3.2-4.2 times as long as base of joint VI. Antennái hairs on joint in maximally 7-10 urn long and from one-quarter to two-fifths times as long as basal diamter of joint. Rostrum short, reaching beyond middle coxae, ultimate segment slender, 0.16-0.17 mm long, and from about one and one-third to about one and one-half times as long as second tarsal segment of hind leg, with 2-3 rather long subsidiary hairs. Siphunculi cylindrical, a little tapering, about 0.12-0.15 of body length and 2.7-3.2 times as long as cauda, and 5-6.2 times as long as their width at half length. Cauda with 5 rather long and acute hairs. Eighth tergite with 4-6 hairs. Subgenital plate with 2 long anterior hairs and 15-20 shorter hairs in posterior marginal series. Ventral trochanteral hair short, maximally 15-25 urn long and from about one-third to one-half as long as diameter of trochantero-femoral suture, but only rarely more than two-fifths. First tarsal segments with 3,3,2 hairs. Colour inf life greenish white with distinct wax powdering. Antennae, legs and siphunculi blackish. Measurements in mm: Flagellar joints Si- Cau- .. H.t.
